BOTTLE CLOSURE AND METHOD OF PRODUCING THE SAME.

Application filed December 9, 1926. Serial No. 153,600.

My invention relates to bottle closures and to a method of producing the same.

Generally speaking, the bottle closure of my invention is produced by placing a skirted cap over the mouth of the bottle and about the bottle neck, contracting a ring about the cap skirt by relatively moving adjacent portions thereof oppositely and circumferentially, and holding said ring portions in ring contracting relation by a part of the cap skirt between said ring portions. As my method is preferably practiced, a split ring is employed of circumferential length less than the circumferential length of the underlying part of the cap skirt, the ends of the split ring being held in ring contracting relation by the part of the cap skirt in the gap between the ring ends. These ring ends are desirably crimped into engagement with the cap skirt and also cemented to the cap skirt to reinforce the crimping engagement of the ring with the cap skirt.

The invention will be more fully explained in connection with the accompanying drawing in which Fig. 1 is a perspective view of the upper portion of a bottle equipped with the closure cap of my invention; Fig. 2 is a vertical sectional view on line 22 of Fig. 1; Fig. 3 is a horizontal sectional view illustrating the cap skirt and ring in uncontracted adjustments; Fig. 4 is a horizontal sectional view illustrating the ring and cap skirt contracted about the bottle neck and dies for accomplishing this result; and Fig. 5 is a sectional view on line 5-5 of Fig. 1.

The bottle 1, illustrated, is one which is commonly employed for containing milk or cream. It has an external enlargement or surrounding bead 2 at its mouth. It is customary to provide an annular seat 3 at the mouth of the bottle for receiving a closure disc 4, this closure disc, however, forming no essential part of my invention. A cap 5, preferably paper, is placed over the mouth of the bottle and over the closure disc 4, this cap having a skirt 6 integral therewith which is partially encircled by a split ring 7, preferably formed of metal.

Fig. 3 illustrates the ca and ring in the shape occupied thereby w en these two. elements are first assembled with the bottle neck. The cap skirt is initially fluted as indicated-at 7 except at the panel 7 which is in the gap between the ends of the ring.

When the cap and ring have been properly placed upon the bottle neck, the jaws 8 are simultaneously approached to compress the fluted portions of the skirt into folds, as illustrated in Figs. 4 and 5, and to bulge the ring at intervals, as indicated at 9, portions of the cap skirt being clinched between the sides of the bulges in the ring. By this operation, the ring is contracted about the cap skirt, the end portions of the ring being relatively-moved oppositely and circumferentially for this purpose. The bulges 9 at the ends of the ring place the panel 7 2 of the cap skirt into close contact with the bottle neck, this cap skirt panel constituting, in effect, a continuation of the ring in addition to being a part of the cap skirt, the split I'lllg placing this cap skirt panel under sufficient tension to enable said cap skirt panel to cooperate with the split ring in holding the cap skirt tightly about the bottle neck. The portion of the cap skirt panel 7 in the zone of the ring constitutes a bond serving to hold the adjacent ends of the split ringportions in ring contracting relation, the adjacent end portions of the split ring being held under tension by said skirt panel 7 and the attachments of the ring ends to said cap skirt panel, the ring being tightly drawn against the cap skirt to tightly hold the cap skirt tightly against the bottle neck. The union between the split ring and the cap skirt is completed preferably by patches of sealing wax 10, which is a preferred form of *cement,.which is applied in heated and fluxed condition directly to the bulges 9 in the ring adjacent the ends of the ring and directly to the portions of the cap gripped by these bulges and adjacent to the bulges. Changes may be made without departlng from the invention.

Having thus described my invention, I claim:

1. The method of sealing a bottle which consists in placing a skirted cap over the mouth of the bottle and about the bottle neck; contracting a ring about the cap skirt by relatively moving adjacent portions thereof oppositely and circumferentially; and holding said ring portions in ring contracting relation by a part of the cap skirt between said ring portions.

2. The method of sealing a bottle which. consists in placing a skirted cap over the mouth of the bottle and about the bottle circumferential length of the underlying part of the cap skirt; and cementing the ends of the split ring to adjacent portions of the cap skirt.

4. A bottle whose neck is externally enlarged at the mouth of the bottle; in combination with a skirted cap placed over the mouth of the bottle and about the bottle neck; and a skirt contracting ring about the cap skirt, circumferentially spaced apart ortions of the ring being secured to adqacent portions of the cap skirt, a portion 56f the cap skirt between said ring portions serving as a bond to hold the said spaced apart ring portions in ring contracting relation, said ring being below the enlargement at the. mouth of the bottle.

5. A bottle whose neck is externally enlarged at the mouth of the bottle; in combination with a skirted cap placed over the mouth of the bottle and about the bottle neck; and a split skirt contracting ring about the cap skirt and less in circumferential length than the circumferential len h of the underlying part of the ca sklrt, the ends of the rin being secure to adjacent portions of the cap skirt, the portion of the cap skirt in the gap between the ring ends serving as a bond to hold these ring ends in ringcontracting relation, said ring being below the enlargement at the mouth of the'bottle.

6. A bottle whose neck is externally enlarged at the mouth of the bottle; in commouth of the bottle and about the bottle neck; securing one portion of a ring to the cap skirt; contracting the ring about thecap skirt by effecting relative movement be tween said portion and another ring portion oppositely andcircumferentially; and directly applying cement to the latter ring portion and cap skirt.

8. The method of sealing a bottle which consists in placing a skirted cap over the mouth of the bottle and about the bottle neck; securing one portion of a ring to the cap skirt; contracting the ring about the cap skirt by affecting relative movement between said portion and another ring portion oppositely and clrcumferentially; directly applying cement tothe latter ring portion and cap skirt; and holding each of said ring portions under tension by its attachment to the cap skirt.

In witness whereof, I hereunto subscribe my name.
